Amanda,
You can try out our app for performance at www.ingenuity.com.my/product-fms-demo.asp.
Logon is demo, pwd is demo.
App logon is ADMIN, pwd is ADMIN.
From our experience, there's a limit to the number of instances that the VFP app can open. About 10-25 instances before the server runs out of memory.
We also deploy college management software via this same mode to universities and colleges in Malaysia.
HTH
